The writer has outlined a methodology that makes possible accurate classification of categories of stellar spectra not dealt with in detail in the MK System. This has been done by introducing a concept which is labeled the MK Process - a procedure which makes possible the construction of an indefinite number of new systems of spectral classification. Each of these new systems is autonomous, and independent of the MK System - and of each other.
Bringing these new systems into operational existence will make possible precise classification of the very great majority of all stellar spectra in our Galaxy and those observable in the nearest external galaxies.
